Secured on each end of shafts 66 and 61 is a bracket 02 by any suitable means such as set screws 63. This bracket has arms and 65 be penetrated by piston shafts 66 and 61. a By referring to Figure 3, the details of ,each' of these members on bracket 62 are more clearly in the lower side ther eof which are adapted tp '2! shown. Both arms 64 and as of bracket "are identical as shown in Figure 3 and the description of one will sufllce for both, however, it might be stated,that the one shown oh the right-hand side of Figure 6 is 'shown in raised or inoperative posi 39, tion, whereas, the one to the le ft of shaft 66 is shown in, operative position or engaging the pis- .46 isiocked thereon by any ton shaft is. a a Each of the members 66 and 65 has a suitable bore 16 therein in which is mounted a pin 11,

' 86. This bin '11 has a collarp11a integral therewith whichlimits the downward movement of spring 16 which is disposed around the pin. A suitable plug 16 is secured in theupper portion of bore 16. said plug'16 being penetiatedby the pin 11. It

46,. might be stated. that this plug also confines the spring 16 within the bore 16 and normally tends to force the pin 11 downwardly against one of the piston shifts. The upper end of pin 11 has threadably secured thereto a member 66 which suitable means such as Mounted inthe upper portion. of members 64 8111185 is a pm 62. It is seen that this pin 62 is adapted to contact t e lower sideof the mem- 9. her 6 when it is des ed that the particular pisto be in inoperative position, asshown in the a position afs shown righthand portion nf Figure 3, whereas, when" it is desired that thevpiston be engaged. with the scotch'yoke 66, the member 66 is caused to assume the left hand portion of Figure 3 where thepin 62 penetrates a suitable- 110103 66111 the member .66. It is therefore seen that when it is desired to disengagea piston shaft from the bracket 62 that bypulling 'upwardly. on

h of the pistons 66 and 61.

, 66 and 61 are slidably mounted in suitable sleeves 61 and 66, said sleeves 61 and 66 being confined in housing 66- by' any suitable means such as nuts 66 and 6| respectively. PThe housing.v 66 is secured tothe top of frame I6 by any suitable means such as s tud bolts 66a. It is 'seen that as shown in Figure 3;v

ings 61a and 66a respectively into the. inside of I sleeves 61 and 66; I Y -By referring to Figures 4 and 5 it is seen that a V-type housing isiprovidedwhich has secured to 5 the upper ends thereof suitable grease containers." The grease container 66 is secured to the r upper portion of housing 66 by any suitable means such as stud bolts 66; whereas, a bracket 61 is secured to the upperjportion of housing 66 by any secured to bracket 61 is the container 66 which is shownin elevationin'Figure 4, The container 66 has therein a suitable piston I66 which forms two compartments I M and I 62. The compartment I6I is adapted. to contain compressed air which is forced through a suitable valve I66 whereas, ,the lower compartment I66 contains the grease. It is also noted that a suitable stra'inefl66 is secured in the lower portion of bracket 61 which prevents tion thereof a strainer loa'whieh' is similar in all 30 respects to strainer I66 and answers the same purpose. The container 66 is adapted tobe used with especially heavy greases in lubricating bearings and the like, -whereas,.the containers 66, are used in ordinary lubrication where atmospheric pres- ;su'rejis "sufllcient to force the greasedown into compartment 66. I I Y It is seen that by providing this special V -type housing such as 66, that much less space is required to mount a grease gun. Itis further seen that the scotch yoke 66 can be mounted to drive either all of the four cylinders as shown in Figure 2 or it can be caused to drive only one cylinder at a time by manipulating the mechanical latches Another housing 66 withcontainers 66 and 66 mounted thereon is secured to-the other end of frame I 6 and a repetition of the description is not deemed necessary since the parts are identical to;

the parts already described. s

Bearings 66 and have integral therewith and extending upwardly therefrom supports Ill and H6. Mounted on top of these bearings ispa box I I6 which has thereinan ordinary storage batte y II1 for driving the "apparatus. Secured w the side of box no is an ordinary plug H6 in which is adapted tobe inserted an ordinary socket from thepower line. Connected to plug III are'wires I I6 and I26 which lead into the charging mav suitable means such as stud bolts 66.- Threadably 10 undesirable obiects from 'passing through and 2 chine I2 I, said charging machine I2I' being se cured to the inside of box] I6, Another wire I22 leads from the other side of charging machine III to a switch I26 and the other side isgroundedas at I26.- I

' The switch in is hdmieu'y opened but when it M is desired to connect the socket I I6 to a source of electrical energy to charge the battery I I1, theswitch-I I6 is closed. Anijther wire I26 leads from the charging'box HI and has one endsecured to an ammeter I21. Leading from the other side .2

r the ammeter is a wire l26whieh is-secured to I terminal I26. Lea'din'gf'rom terminal I 26 is a wire I 66' which is connected to one side of a suitable solenoid switch I6 I said solenoid switchbeing normally. held open by means of a suitable. spring byfrferri fi to Flgure'i, sleeves 61 and 66 have chambers'62 and 66 surrounding them in which the is allowedto flow; and,from these 75 chambe" -the grease is forced through the openme Leading from t e other side 'oi the switch.

mf isawire I82 which is also connected battery I Ila bar I81 leads to the ground I a.

Leading from terminal 123 is a wiretI30 which side of switches I44 are connected wires I41 said wires I1 having their-other ends secured 'to another bus bar I48. Busibar I48 is also securedv to the side of box II8v and has disposed between thebox and the bar another suitable insulating block of material I49. Secured to bus bar I48 as at I50 is a wire II which leads to coil I52 disposed within the box I53. From'the other side of coil I52 is a wire I54 which leadsto a suitable ground I55.

Another pair of wires I51 lead from bus bar I, saidwvires 151 having their upper endsconnected to a pair of switches I58, and tothe other side of these switches are connected wires I60 isallowed to flow from battery II1 to wires I36,

I39, bus bar I, wire I43, switch I44, wire I41, bus bar I48, wire I51 and coil I52 to wire I54 to round I55. When the current flows through coil I52, this coil is energized which causes the switch I3 I to connectthe wires I30 and I32 which completes the circuit to the motor andcauses the current to flow from the battery II1 through wire I 36, wire I30, switch I3l, wire I32, motor 21,

'wire :31. to ground I35. It s evident that by closing either of switches I58 that. a similar operation will take place and the motor will be started;

Figures 7 and 8 show a., detail of the nozzle usedwith this apparatus in which the current will be vautomatically turned on and the motor started upon the opening of thevalve to allow the grease to flow from the container. This nozzle comprises a conventional fitting I88 through which the grease is allowed to flow and which fitting is applied to the parts to be lubricated. This fitting is threadably mounted in member IBI which has therein a bore I82, said bore having mounted therein a conventional com-- pression spring I 83.- The right-hand end of this here is closed by means of plug-I84 which is threadably mounted in the right-hand 'end thereof and slidablymounted in plug I84 is a' pin I85. Secured to the-left-hand end ofpin.I85 is a valve I06 which normally closes the opening in the plug I84. 1

Pivotally secured as at I81 arelinks I88 and 7 its, the other end of said links being pivotally has integral therewith a shoulder I85a disposed on one side of the lever I 9| and a suitable nut I85b disposed on the other side of the lever.

The other end of lever I9I is pivoted as at I92 to a link I93. This link "I93 is inclined upwardly' in Figures 7 and 8 and is pivotally secured a to the motor 21. Another wire I84 leads fromsaid m0- 7 tor and is grounded as at I35. From I23 wire I38 leadsfto the battery H1 and from 'as etm to a m; netetemyseeurediith in em: m isa cylindrical member as m which is fixedly mounted member 181. v J Theleft-handend of member I81 is threadably secured to another-mem er m which is also fixedly mounted'within cylindrical member I08. It is seen that member I88 has its righthand end threadably secured in member 288, said member 208 being threadably secured in the. end

was

of member I 8I whereas the left-hand end ofmember I88 is rotatably confined within memb'ers I81 and I98. Asuitable washer III is did-f posed between the shoulders l88aI and member I98. The left-hand end of fitting I88 has thread-l ably secured thereto another fitting 284 which, in

turn, is secured inside of hose 288.

It is seen that by having member I88 rotatably mounted within members 181 and I88, and also having cylindrical member I88 rotatably mounted within sleeve I85, that the fitting I80 and its associated parts may be rotated about 'the longitudinal axis of hose 205.. and any particular position maybe assumed by the end of the nozzle without twisting or distorting the hose.

It is further seen that the cufif I95 has -an enlarged ring I851: integral therewith whose lefthand surface '(Figs. 7 and 8) normally contacts aneiectrical button 206 at all times. Button 288' is slidably mounted in housing 201 and this button has ,secured to the other end thereof an 80 L-shaped member 208. Secured to L-shaped member 208 is a block' of hard rubber or insulating material 200, said'block 200 having mounted on the upper side thereof a member 2I0 which has projections 2H and 2I2 integral therewith which are adapted to contact terminals M8 and '2 respectively, when the switch is closed. A spring 215 is mounted in block 200 which normally pushes member 2I0 upwardly at'all times against the insulating ,block 2I1 which contains theterininals- 2I3 and 2". The casing 281 is disposed between the members 2| 8 and 2", said members 2I8 and 2I9 being secured around the hose 205 by any suitable means such as rivets 2204 It is evident that when handle I8l is pushed towards the member I8l that the'cui! I85'will be forced to the left ,which will cause th e terminals 2H and 2Y2 to contact the terminals 2" and 2 I4 which will complete the circuit andcause the motor to start pumping grease.

end abutting casing 201 and the other end abutting the large portion of the button 288.

Not only is this-nozzle provided with a awiveled .joint so that the nozzle I88 may bevturned in anydirection, but it also'provides-means wherebya certain amount of backpressu're may be built up inthe line and by pressing downward-'- fl 1y ,a slight amoimt onlthe handle I8I the valve I85 will be opened but the connection will not .bemade between the terminals 2, 2l2, 2" and 2" to cause the motor to start. This will allow a. number of points to be greased with the back pressure without starting-the motor each time a point is greased. The distance between terminals 2I-8 and 2 makes it pomble toopen the valve I86 without causing contact points 2| I and M2 to contact them.
